FAUCET.

Specication of Letters Patent No. 32,201, dated April 30, 1861.

To all whom it may concern:

Be it known that I, J. NEUMANN, of No. 3l Mercer street, in the city,county, andA State of New York, have invented a new and ImprovedBeer-Faucet; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure l is a longitudinal central section through the improved faucet,representing the valve in two positions. Fig. 2 is a section in thehorizontal plane indicated by the red line 353/, in Fig. l.

Similar letters of reference indicate corresponding parts in bothfigures.

This invention relates to a new and useful improvement in faucetsintended especially for beer barrels where the barrels are kept in thecellar and the beer pumped up by a pump in the store, whenever it iswanted. It is a very common thing for the pumps to become inoperative onaccountof a very slight leak in their pistons, and the column of beer isdropped back into the barrel.

The object of my invention is to construct a faucet that will preventthe beer once drawn through it from returning through it again into thebarrel and at the same time which will allow beer to be drawn from thebarrel either with a pump or without a pump like a common beer faucet,as will be hereinafter fully described.

To enable those skilled in the art to make and use my invention Iwillproceed to describe its construction and operation.

A. represents the conical faucet tube or that part of the faucet whichis driven int-o the barrel.,

B. is a hollow .cylindrical portion which forms a chamber from which theliquid .escapes into the side tube C. to which the pipe is connectedleading to the pump. The tube A. is closed at its extreme end with theexception of a number of small perforations which form a strainer toprevent any substance from getting into the body of the faucet whichwould be liable tok choke it up, and prevent a free flow of liquidthrough the faucet.

The longitudinal bore a, of tube A. communicates with the chamber B.through the orice o, Fig. l, which has a valve c, over it that opens andcloses the orifice alternately as the piston of the pump rises andfalls. The vertical central stem d, of valve c, passes loosely into ahole c, in the axis of screw stem D. which keeps the valve in place andallows it to rise and fall. freely, when the stem` D. is in the positionrepre-sented in black lines Fig. l. Screw stem D. has a circularenlargement g, on its lower end which is covered on its top surface witha packing it, and on the upper end of stem D. is fixed a handle E. foroperating the faucet.

Stem D. is tapped through the center of a nut or cap G. which isscrewed'down tightly on the top of cylindrical portion B.

The tubular portion C. communicating with chamber B. shown in Fig. 2 ofthe drawings, has a male screw thread out on it to receive the couplingnut 7c, which secures the pipe C. to the end of the tube.

lVhen the stem D. is screwed down tight-ly, as represented in Fig. l, ofthe drawings, in red lines, the enlargement g, presses the valve c, downhard on its seat and prevents any liquid from passing through thefaucet. l/Vhen this stem D. is unscrewed so that. the packing iz., willpress against the bottom of nut G. the valve c, will be allowed to moveup and down freely and it will be readily seen that when the pump pistonis drawn up, the liquid will pass through the faucet tube under valve c,and through chamber B. Then instantly the pump piston is depressed thevalve c, will be closed by the weight of the column of liquid above it,and the liquid will not be allowed to flow back into the barrel, and theinconvenience hitherto experienced in pumping up beer from cellars willbe effectually prevented. Having thus described my invention what Iclaim as new and desire to secure by Letters Patent is The chamber B. onfaucet tube A. having arranged within it the valve c, and the screw stemD. with its enlargement g, all arranged and operating substantially as,and for the purposes, herein set forth.

JOHN NEUMANN.
